SPECIFICATION forming part of Letters Patent N o. 383,571, dated May 29,1888.

Application sied october 7,1896. serial Naming. (No model.)

To aZZ whom it may concern.'

Be it known that I, HENRY E. GRIFFITH, a citizen of the UnitedStates,residing at Roches` ter, in the county of Monroe and State of New York,have invented a certain new and useful Improvement in Ash-Sifters; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the drawingsaccompanying this specification.

My improvement relates to rocking sifters; and it consists in theconstruction and arrangement of parts,hereinafter more fully described,and specifically claimed.

In the drawings, Figure 1 is a side elevation, partly in section, of theapparatus, Fig. 2 is a plan view of the same. Fig. 3 is an end elevationof the apparatus with the bottom portion broken away.

A indicates the base, and B B two standards that rise from the same andsupport the rocking frame and boxes.

C is the rocking frame, made in skeleton form and provided with journalsa a, that rest in slots b b of the standard, by which means the framecan be rocked forward and back.

D is a lever attached rigidly to one side of the rocking frame, by whichthe machine is operated. Thislever rests inside of the standard B and inproximity thereto.

E and F are the two boxes or receptacles mounted on top of the rockingframe and receiving motion with it. The box E, which is the ash-box, hascleats c o nailed on its under side, which cleats rest outside of theends d d of the frame and hold the box from slipping 0E endwise as it isrocked up and down. The

box F, which is the cinder-box, rests on top of box E and has shouldersf f,that set down into the top of box E and prevent it from slippingloff. The box F is provided with a screen, g, through which the ashes aresifted as the apparatus is rocked. The boxes are held against sidemovement by resting closely between the standards B. They are providedwith handles h h, by which they can be removed and carried away, eitherboth together or each separately.

G is an arm pivoted at la to the lever D, so as to turn freely. It isprovided with a rightangled open clamp or stirrup, m, near the lever, asshown. When turned down, the arm rests on top of the box Fand holds itdown, so that the boxes are secure on the rocking frame when in use.When turned up, as shown in dotted lines, Fig. 3, the open clamp orstirrup m embraces both the lever D and standard B, locking said parts,freeing the boxes, and enabling them to be opened to insert the ashes orto be removed and carried off to dump the cinders and ashes. The arm Gis locked down on top of the receptacles to hold them in place by meansof a bar or wedge, p, inserted between the lever D and the stirrup m, asshown in Fig. 3.

Having described my invention,what I claim as new, and desire to secureby Letters Patent, is-

In an ash-sifter, the combination, with the standards B, rocking frameC, and boxes E F, of the lever D, attached to the rocking frame, and thebar G, pivoted to the lever and provided with the right-angled stirrupm, said bar fastening the boxes to the rocking frame when turned down,and fastening the lever tothe standard when turned up, as herein shownand described.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
